Aggregate Impact Value- Passing through 12.5mm IS Sieve
– 100%- Retention on 10mm IS Sieve –
100%The sample should be oven-dried
for 4hrsAggregate impact value = (B/A) x
100%
Aggregate Abrasion ValueAggregate abrasion
value = (A-B)/B x 100%.
Soil TestDetermine The Maximum Dry Density And The
Optimum Moisture Content Of SoilDetermining Water Content In Soil - Oven Drying
MethodDetermine The Specific Gravity Of Soil

W1=container weightW2=wet soil specimen in the containerW3=container with the dry soil sampleThe water content
w = [W2-W3] / [W3 -W1]*100%

Difference Between Flexible and Rigid Pavement
Flexible pavement Rigid Pavement
Load is transfer by grain to grain. Low strength. Low life Span. High maintenance cost. Rolling of surface is needed. Damaged by oils and certain
chemicals.
Load transfer is not exists. High strength. Life span is more. Low Maintenance cost. Rolling of surface is not needed. No damage by oils and greases.
AdvantageFlexible Rigid
Repair of flexible pavement is easy.
Additional thickness added any time.
The flexible pavement is smooth.
Tolerates a great range of temperature.
Durability of rigid pavement is good.
Life cycle of rigid pavement is long.
Withstand repeated flooding and surface water.
DisadvantagesFlexible RigidLoses some flexibility and
cohesion with time.Needs resurfacing sooner
then PC concrete.Not normally chosen where
water is expected.The life of flexible pavement
is short.The maintenance cost is high
May lose skid surface with time.
May fault at transverse joints.
